- What’s happening in corn disease research?
Alison Robertson, professor and extension crop plant pathologist for ISU presents results from on-going research in the Robertson Lab. In 2020 the lab had trials that evaluated the impact of cover crops on seedling disease and corn growth and development, in addition to fungicide trials for Physoderma and foliar disease control.
Wednesday, December 30 at 9 to 10 a.m.
- Making the most of your manure nutrients
Brian Dougherty, extension agricultural engineering field specialist at ISU Extension and Outreach in Dubuque, IA hosts this webinar and will provide information to help you maximize the value of liquid manure as a nutrient source for crops. Tips on manure application strategies, equipment maintenance, and using cover crops will be shared. Results from research on manure application timing, cover crop nutrient uptake, and nitrification inhibitors will be presented, including water quality and yield data.
Wednesday, December 30 at 1 to 2 p.m.
- U.S.-China agricultural trade: The way forward
Wendong Zhang, assistant economics professor and extension economist at ISU provides an update on the conditions of U.S.-China agricultural trade after the November election and before the end of the phase one trade deal year 1 target. Wendong will also discuss the ongoing agricultural transformations in China and the future of U.S. agricultural exports to China post COVID-19.
Thursday, December 31 at 9 to 10 a.m.
- Tractors and central-fill planter fire inflation pressure effects on corn yield and soil physical properties
Mehari Tekeste, assistant professor for agricultural and biosystems engineering at ISU will host this presentation. Over the past decade, the agricultural farm equipment keeps getting bigger in size along with the concerns on soil compaction from excessive loading on compactable soil conditions. Issues related to soil compaction and its impact on crop yield from center rows and wing rows from central-fill planter equipment have been of concern to crop growers. Recently newer tire technologies, such as Central Tire Inflation System (CTIS) and IF/VF Radial Tire Pressure, have been introduced on tractor tires and row-crop planter tires as alternative solutions to Standard Radial Tire Pressure setting for increasing ground contact area and minimize yield impact from soil compaction. The session will show crop yield and soil property differences when comparing Central Tire Inflation System and IF/VF tires with standard radial tires on a MFWD tractor and 24-row central fill planter.
